IMPROVEMENT IN RAI LPLOAD-LAM PS.

Specification forming part of Letters Patent No. 42,853, dated May 24,1864.

To all zrzom it may concern Be it known that I, LEWIS 11ovER,of Chicago,in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Railroad Lamps and Lanterns; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof', reference being had tothe accompanying drawings and theletters and Ijgures marked thereon, which form part of thisspecification.

In said drawings, which are hereunto annexed, Figure l represents avertical central section of my invention; and Fig. 2 a top view of thesame, the shade B being in section at the line x in Fig. 1.

The nature of my invention consists in a novel arrangement for raisingand lowering the wick of the lamp or lantern without removing the shadeor globe thereof', while at I the same time the lamp may be held in anup- Iight or vertical position when being attached to the shade orglobe, and by a simple adjustment the connection with the Wick may bebroken, so that without the proper readjustment the wick cannot beregulated or disturbed, thus preventing the intermeddling of persons whohave no business with the lamps.

To enable those skilled in the art to under- I will proceed to describethe same with par ticularity.

A represents the lamp proper or oil-cup; B, the glass shade orprotector; C, the mef tallic top or chimney; l), the metallic attachmentto the base of the shade B, whereby slid shade is fastened to the lampby means I of the springs F and projection lil; and G. is the wick-tubeof the lamp. As all these parts have no particular reference to myinvention,

and may be constructed in any of the known forms, no parlicnlardescription is needed. I

The shaft a, upon which the rougbened wheels :r .r are tixed, terminatesinside of the casing ot' the lamp or lantern, and is provided with asquare head or button, as shown. The shaft b, provided with the button cfor convenience in operatingthe same, passes through a I suitableopening in the casinginto the interior i it I and is provided upon theend, as shown, with a concave head adapted to receive the head upon theshaft a. The concave head upon b, however, is kept away from a by theoperation of the spring d, arranged, as shown, between the exterior ofthe casing D and the button c.

For the purposeot' enabling the operator to adjust the two shafts a andb so as to connect with each other, the arm or projecting bar e isemployed, being fixed to the casing D. When the'wick requires adjusting,the operator turns the lamp Within the casing from any position, as thatindicated by the red lines in Fig. 2, until the bar or shaft a strikesagainst the arm e, when he presses the shaft b inward until the concavehead thereof receives the head ot' a, and then bya rotary motion of b,the same motion is given to a, and the wick readily adjusted. Byrelieving the shaft I) from the pressure the spring d im'- mediatelydisconnects b from a, when the lamp may be moved back to the positionshown by the aforesaid red lines, when the turning of the shaft I1 canhave no effect upon the wick.

This Ainvention is equally applicable to lamps and lanterns.

Having described the construction and operation ot my invention, I willnow specify what I claim therein and desire to secure by LettersPatentl. The combination of the shaft a with the adjustable shaft I),constructed, arranged, and

y operating substantiz-illy as and for ,the purposcsspccilied and shown.

2. In combination with the adj ustablc shaft b, the employment of thespring d, arranged and operating` as and for the purposes shown anddescribed.

3. 'Ille employment oI" the arm c, in combination wi h the shafts a andl), as and for the purposes shown and set forth.
